Oct. 24, 1933. E. s. GARVEY FLUID DISPENSING DEVICE Filed June 9, 1955 (3 5 6 Z/ 9 I 4 L 4 f0 ii I 7 M Z; 5 /4 2g Patented Oct. 24, 1933 STATES PATENT OFFICE '11 Claims.

This invention relates to fluid dispensing devices, and as an illustration of the invention I will hereafter refer to an inscribing instrument in the form of a fountain brush provided with a ,5 self-closing valve which controls the delivery of fluid to the brush. This valve moves toward and away from its seat in response to the ordinary movementstransmitted to" the brush when the device is in service.

In the preferred form of the invention, a normally closed check valve is free to tilt on its seat in response to movements of the fluid dispensing device.

, One of the objects is to provide a simple, and convenient means for controlling a loose valve of this kind, so as to regulate the deliveryof fluid. The valve is free to move in a suitable housing, and its movements are limited by a stopmember adjustable towardand away from the valve. The means for transmitting movement to the stop member preferably includes an operating member exposed at the exterior of the device, so that the user can very easily and quicklyregulate.

the flow at the loose valve. The external operating member can be used to retain the valve on its seat, and thereby prevent leakage when the device is not in service, but another important advantage lies in the control of a loose valve by means of an exposed operating member whereby the flow can be most conveniently, regulated to accurately obtain the desired results.

Another object is to prevent leakage at the means for transmitting movement from the external operating memberto the internal stop 7 .35 -member. A further object is to provide a device of this kind wherein the several parts can be easily assembled and taken apart.

With the foregoing and other objects in view, the invention comprises the novel construction, combination and arrangement of partshereinafter more specifically described and illustrated in the accompanying drawing, wherein" is shown the. preferred embodiment of the invention. However, it is to be understood that the invention comprehends changes, variations and modifications which come within the scope of the claims hereunto appended.

Fig. 1 is a side elevation of a f embodying the features of this invention Fig. 2 is a fragmentary section ona larger scale, taken approximately on the line 2-2 in Fig. 1.

Fig. 3 is a section on the line 3-3 in Fig. 2 showing the parts adjusted to retain the valve in its closed position.

normally ountain brush I Fig. 4 is a section taken approximately on the line 44 in Fig. 2.

Fig. 5 is a view similar to Fig. 3, showing the stop member positioned to permit tiltingof the 7 check valve.

To illustrate one form of the invention, I have shown a fountain brush comprising a reservoir 1,

a brush tip 2 and a valve housing 3 connecting the reservoir to the brush tip. The lower end of the reservoir is screwed onto the top of the valve housing. The brush memberis provided 4 with a threaded ring 4 screwed into the bottom of the valve housing.

The ink, or other fluid, is introduced into the reservoir, and it flows through a passageway 5 7.0, in the valve housing and thence to the brush member. 7 e

The means for confining the fluid in the reservoir includes a check valve '6 having a stem '7 suspended from a valve seat 8. The valve is free to tilt on its seat, and the stem 7 may be, termed a pendulum which swings, or vibrates, in response to movements of the device, so as to own and close the valve when the brush is in service.

' In this form of the invention, the operator grasps the reservoir 1 while moving the brush over a stencil, and the movements of the free valve depend partly upon the speed of the device and partly upon the changes in the direction of its movements. These conditions will vary in different kinds of work, and in the use of a brush, there will be no uniformity in the motions of different operators engaged in the same work.

The problem lies in producing a device wherein the flow can be quickly and accurately regulated, to immediately meet all of the conditions as they arise when the device is in service.

The desired regulation can be obtained by limiting the movements of the free valve, and I will now describe details of a device which meets all of these requirements, with the understanding that the invention is defined by the appended claims, and not by this description of details.

To limitv the tilting movements of the valve 6, a pair of horizontal disks 9 and 10 is located in a circular guideway above the valve, said disks being integrally united by means of a vertical member 11, and provided with openings 12 for the passage of fluid through the disks. The lower disk 10 lies immediately'above and adjacent to the valve 6, and it serves as an abutment to limit the movements of the valve.

To adjust this stop .device toward and away from thevalve, a cam. 13 in the form of an eccentric embraced by the disks. may be provided with a horizontal operating shaft 14 at one side of the cam, and a short extension 14' at the opposite side, said extension being journaled in the valve housing.

The shaft 14 passes through an opening which extends laterally from the passageway in which the valve is located, and this opening is threaded to receive an inner threaded member 16 which surrounds the shaft and an outer threaded mem ber 17 also surrounding the shaft. The inner threaded member is firmly seated in this opening to prevent leakage at the screw threads, and it has a recess 18 to receive packing around the shaft, while the outer threaded member 17 has a gland 19 extending into said recess 18, as shown in Fig. 4. Both of these threaded members form bearings 'for the shaft 14, and they are notched as shown by dotted lines in Fig. 2, to receive a screw driver, or the like, whereby they are inserted into and removed from the threaded opening. I

This opening is large enough to permit insertion and removal of the eccentric member 13 when the threaded members 16 and 17 are removed. These threaded members cooperate with each other to prevent leakage at the shaft and screw threads when the device is in service.

The shaft l -i has an operating member 21 exposed at the exterior of thedevice, and movable to adjust the stop member 10 toward and away from the valve 6. This operating member may be removably secured to the shaft 14, by means of a screw 22, so that a suitable tool can be conveniently used to remove the threaded members 16 and 17.

, It will be understoodthat the external operating member 21 can be very easily and quickly adjusted to regulate the discharge of fluid from the reservoir 1, and that this adjustment can be readily made to obtain the desired flow which will depend partly upon the kind ofwork to be done, and partly. uponthemanner inwhich the individual operator manipulates the device. In any event, the user will merely adjust the external operating member to control the loose valve 6 which will vary the flow in accor dance with the varying conditions arising in the use of the brush.
